BluePrint Release 5.1 is the latest in customer driven releases. All new features and enhancements were requested by existing customers. Over the preceding year, DownStream Technologies queried our customer base for new ideas or enhancements to existing features. Each release of BluePrint contains many user requested features as well as quality enhancements. Customers who are eligible for 12.1 & 5.1 are able to access these new builds.
